Mn reduction's
WebThe oxidation # of Mn changes from 2+ to 4+. The oxidation # for O changes from 0 to 2-. The oxidizing agent is Mn and the element that gets reduced is O. The half-cell oxidation reaction is Mn2+ + 2H 2O = MnO2 +4H + + 2e and the half-cell reduction reaction is 1/4 O 2 + H + + e = ½ H 2O. If equilibrium is achieved in seawater (pH 8) the E0 WebManganese is mainly used in metallurgical processes, as a deoxidizing and desulfurizing additive and as an alloying constituent. It is also used in the production of dry-cell …
